Diemaco was a Canadian defence company based in Kitchener, Ontario, that manufactured the C7 family of rifles under a licence from Colt. The company was formed in 1974 effectively replacing the arms supply from government owned Canadian Arsenal Limited. It was acquired by Colt Defense on May 20, 2005, in an $18.2 million purchase from parent company Héroux-Devtek Inc, which had purchased Diemaco in 2000.[1][2]
